1. A stapling device comprising:
an elongate body having a proximal portion and a distal portion;
a clamp slide assembly having a distal portion that defines a curved pocket, the distal portion of the clamp slide assembly including spaced walls that define a linear section of the distal portion of the clamp slide assembly, the linear section of the distal portion of the clamp slide assembly positioned on a first end portion of the clamp slide assembly and defining linear channels; and
an end effector supported on the distal portion of the elongate body, the end effector including:
an end effector frame having a U-shaped configuration and including a distal transverse portion, a proximal transverse portion, and a longitudinal portion, the longitudinal portion connecting the distal transverse portion to the proximal transverse portion to define a gap between the distal transverse portion and the proximal transverse portion, the distal portion of the clamp slide assembly positioned within the gap and movable between retracted and advanced positions;
an anvil assembly supported on the distal transverse portion of the end effector frame; and
a cartridge module removably received within the curved pocket of the clamp slide assembly, the cartridge module including a module body having a curved configuration with a linear section, the linear section of the module body including linear ribs that are received in the linear channels in the linear section of the distal portion of the clamp slide assembly when the cartridge module is loaded into the distal portion of the clamp slide assembly.
